This clay has been traditionally used in Panama for casseroles to cook over firewood; for water containers called Tinajas that were partly buried undergroud to keep the water fresh for drinking; as clay tiles for roof or flooring; as decorative and ceremonial artifacts amongst other things. Trasto extends the tradition with these plates made and painted by hand. They are fired in an electric kiln at about 1800F (aprox. 1,000C). home pvens barely reach half this temperature so, you can bake with them with no problem. We have even added chamota (broken recycled plates) to the clay mixture to make them ovenproof, so it can be transferred directly from the stove to the oven.
